' Application filed July 27, 1926. Serial No. 125,298.

This invention relates to new and useful through the center of the casting is an openimprovements in heaters, and particularly ing 17. Also formed in the upper face of to heaters which use liquid fuel. the casting, outwardly of the recess, and in One object of the invention is to provide concentric relation thereto, are the downa heater of the type which is adapted to wardly stepped circular grooves 1S, comheat a single room, and wherein liquid fuel munication betweenthe recess and upperis burned with the maximum heat but with most groove being established by means of the expenditure of the minimum amount the transverse notches 19, formed in the of fuel. upper edge of the surrounding wall of said le Another object is to provide a device of recess. Seated on the said wall of the rethis character which is simple in construccess is a block 20, and resting on the upper tion, durable and effective in its operation, face of vsaid block is the lower face of the and which can be manufactured at a low downwardly tapering vaporizing chamber @0st, Y 21. This chamber is closed except for a Another object is to pro-vide a device of threaded opening 22, in its bottom, said this character wherein the vaporizing chamopening registering with an opening 20, in ber and the gas flame are so located with said vblock 20, and the opening 17 in the respect to each other that the maximum of center of the casting to receive the vertical heat from the-flame is `directed against the tube 23, said tube being screwed into the lo walls of the chamber, with the result that opening 22, as clearly seen in Figure 2, of the liquid fuel is more quickly vaporized, in the drawings. The lower end of the tube 23 said chamber, and the use of the fuel for projects below the lower face of the caststarting reduced to a minimum. ing 15, and is both internally and externally Other objects and advantages will be apthreaded. A nut 211 is engaged on the ex- W51 parent from the following description when ternal threads, and serves to bring the casttaken in connection with the accompanying ing 15, the block 20, and the chamber 21 into drawings, rm contact with each other. 1n the sides In the drawings: of the tube 23, within the recess 1'6, are the Figure 1 is an elevation of the device, openings 211 which establish direct communi- 85 :zo partly in section. cation between the tube and the recess. The Figure 2 is an enlarged vertical sectional upper portion of the tube 23 is disposed view of the burner. adjacent the top wall of the combustion Figure 3 is a horizontal sectional view on chamber, so that oil which is discharged into the line 3-3 of Figure 1. the chamber may overflow into said tube and es 35 Figure t is a top plan view of the heatescape to the recess 16, from whence it flows ring, through the notches 19 into the circular Figure 5 is a detail view of the rectangugrooves 18.

The that the oil therein will vaporize and flow upper edge of the wall is formed with a out through the tube 23, to the recess 16, and

The crest. rlhe combination of the wall 11 and oil is conveyed to the chamber 21, from an the dome 13 forms a combustion chamber. elevated tank (not shown), by means ofthe rlhe wall 11 is formed with an inwardly expipes 25 and 27, the former of which is los 5o tending flange 11', on its lower portion, and screwed into the lower end of a centrally supported on this flange is the peripheral apertured plug 26, which is screwed into edge portion of the casting 15. The interthe lower end of the tube 23, while the latter mediate portion of the casting is of greater is screwed into the upper end of this plug thickness than the remainder, and in the and extends upwardly within the tube 23, im upper face of this central portion there is and beyond the upper end of said tube where formed a recess 16, and formed vertically it is bent laterally and downwardly to deliver the oil into the chamber. Leading downwardly from the lowermost of the grooves 18 is a drain or overflow pipe 18, which carries oilA the excess of oil fromvthe grooves. rlhe inner portion' of the casting 15 is in the form of a hollow ring 15, and in the upper portion of the ring are 'formed the openings 28, and connected to the lower side oi the ring is a pipe 29, through which ordinary illuminating gas may be conveyed to the interior of the ring, for burning at said openings 28, whereby to provide a flame for initially heating` the vaporizing` chamber 21, when it is not desired to use the oil. ln this event the operator stops the flow of the oil into the chamber, when the level of such oil rises to a point below the upper end of the tube 23. `When the gas from the vapo'rized oil begins to ll ow from the notches 19, and burns thereat, the operator cuts on' the illuminating gas. lisposed on the casting 15 is a centrally apertured baille plate 31, which directs the risingi air toward the notches 19, whereby to aid in the combustion of the gas or oil.

Disposed above the dome is a horizontally arranged circular hollow heat radiating ring 32, a connectiinbl pipe 32E joining the .inner wall thereof with the' said outlet 1li, o'i the dome. Coiniected to the lower side of the ring 32, at a point opposite to that of the pipe 33, is an outlet pipe 34, said outlet pipe 34 being connected with ythe' upper portion of a hollow rectangular radiator 35, a smoke pipe 36 leading from the lower end of the radiator to a stack or chimney, not shown.

Enclosing the elements hereinbefore described is an outer shell or casing 37, which has the air inlet openings 38 in the lower portion of its walls, and the hot air outletopenings 39 adjacent the upper ends ot the walls. A suitable cover e() is removably secured on the upper end of the casing.

The bottom portion oi? the vaporizing chamber includes a removable blockv 20 which serv-es to increase the thickness of the bottom whereby to more eifectively protect the cl'iamber'ifrom burning out.

What is claimed is:

ri'he combination with a heat generating chamber having' an outlet in its upper end, ot' a horizontal radiator having a continuous passage therearound, a pipe connected tothe inner face ot' oneside portion of the radiator and to the said outlet, a vertical radiator having a continuous passage therearound, a pipe connecting the upper end of the vertical radiator' with the horizontal radiator at a point remote from `lthe lirstnamed pipe, and a smoke pipe leading from the lower end o' the vertical radiator.

In testimony whereof, I aiiix my signature.
